Review on Upgrade your Power Tool: Black & Decker 5140112-17 Switch Kit Unleashed! by Brian Wolf

Handle and switch are different from original. However, the "package" is 100% compatible with previous versions. Please note: it was only after examining the switch itself closely that I noticed a change in the position of the wires. In the original configuration, the power and blade brake connections were made on opposite ends of the switch. At the new switch, the current is switched on on one side and the blade brake is switched on on the other side. A working knowledge and identification of normally open (NO) and normally closed (NC) switches is helpful. or a lengthy process, although I can see the switch causing a few headaches. Hope that helps.
